List of Farm to Market Roads in Texas (600–699)

Farm to Market Road 600 (FM 600) is located in Haskell, Jones, and Taylor counties.

FM 600 begins at I-20 in Abilene and runs in a northern direction along West Lake Road before turning northeast at FM 3308 and turning back north at FM 3034. In northern Abilene, the highway runs near the western shore of Fort Phantom Hill Lake, leaving the city limits north of the FM 1082 intersection. FM 600 runs through rural areas of Jones County, intersecting US 180 east of Anson and has a short overlap with SH 6 through the town of Avoca. After the overlap with SH 6, the highway runs in an eastern direction before turning back north at County Road 223. FM 600 crosses over Lake Stamford before sharing an overlap with FM 618 near Paint Creek. The highway runs through rural areas of Haskell County before ending at an intersection with US 380 on the eastern edge of Haskell.

FM 600 was designated on July 25, 1945, running from US 380 (now SH 6) to a point 8 miles (13 km) to the northeast. On December 16, 1948, the highway was extended further north to FM 142. On September 27, 1960, FM 600 was extended north to FM 618. On October 22, 1962, FM 600 was rerouted over a section of FM 142 south and west to US 380 (now SH 6), while the old route east and south to Lueders was transferred to FM 142. FM 600 absorbed FM 1834 north of FM 618 and FM 1193 south of US 380, extending the highway to I-20.[2][3][4] On June 27, 1995, the section of FM 600 between I-20 and FM 3034 was redesignated Urban Road 600 (UR 600).[5] The designation reverted to FM 600 with the elimination of the Urban Road system on November 15, 2018.[6]

Farm to Market Road 640 (FM 640) is located in Wharton County. The three-mile-long highway starts at FM 102 east of Glen Flora, heads to the north and ends at FM 1161 in Spanish Camp.

A two-lane highway along its entire route, FM 640 begins at a stop sign on FM 102 1.1 miles (1.8 km) to the east of Glen Flora.[69] According to the United States Geological Survey 1953 Glen Flora 7.5' quadrangle map, the intersection is midway between Glen Flora and the one-time community of Sorrelle.[70] FM 640 heads straight to the north-northeast for 0.8 miles (1.3 km) then curves sharply to the northwest.[69] Just after the curve, the highway crosses Baughman Slough, a small watercourse.[70] After going northwest for a short distance, FM 640 bends to the right twice until it is going to the north-northeast. After about 1.0 mile (1.6 km) from the first curve, the highway curves to the north-northwest. For the next 0.9 miles (1.4 km), FM 640 goes in a straight line to the north-northwest. After curving to the left and right, FM 640 goes 0.3 miles (0.5 km) before coming to a stop sign at FM 1161 in Spanish Camp.[69] In its final stretch the highway crosses Peach Creek and there were a number of natural gas wells in the area in 1952.[71]

FM 1161 curves sharply to the northeast at its junction with FM 640 in Spanish Camp

On May 23, 1951, FM 640 was redesignated to start at FM 102 near Glen Flora in Wharton County and continue in a northerly direction to FM 1161 in Spanish Camp. The distance was estimated at 3.1 miles (5.0 km).[68]

Farm to Market Road 646 (FM 646) is a designation that has been used three times. The current use is in Galveston County, from FM 2004 at Hitchcock to FM 517 at San Leon. There is a concurrency with SH 6 in Santa Fe.

The highway begins at FM 2004 in Hitchcock, Texas. It runs north to Texas State Highway 6 in Santa Fe, Texas. It briefly merges with Highway 6, heading northwest, and then branches off and keeps heading north. The highway has intersections with Farm to Market Road 1764 and Farm to Market Road 517 before turning northeast and intersecting Interstate 45 soon after. The highway continues northeast and passes into Dickinson, where it intersects Texas State Highway 3 and turns east before intersecting Farm to Market Road 1266. The highway intersects Farm to Market Road 3436 before turning northeast again. The highway intersects Texas State Highway 146 and passes through Bacliff. Once it reaches Bayshore Drive, it turns abruptly southeast and continues into San Leon. The highway ends at its second intersection with FM 517.

FM 646 was designated on December 17, 1952, from FM 517 south to SH 6 near Alta Loma. It was formerly FM 517,[78] and before that, FM 520.[79] On October 31, 1958, the road was extended 6.8 miles (10.9 km) to the Brazoria County line. On December 5, 1961, the section of FM 646 from SH 6 to the Brazoria County line was transferred to FM 1561. On October 8, 1964, the road was extended to FM 2004, replacing a section of FM 1561 (which was cancelled, as the remainder of FM 1561 became part of FM 2004) and creating a concurrency with SH 6. On May 25, 1976, the road was extended north 1.6 miles (2.6 km) to I-45 and FM 3002. On February 8, 1980, the road was extended to FM 517 southwest of Bacliff, replacing FM 3002. On July 20, 1982, by district request, the road was extended to FM 517 in San Leon, replacing a section of FM 3436. On June 27, 1995, the section from SH 6 to UR 517 at San Leon was transferred to UR 646, but was changed back to FM 646 on November 15, 2018.

FM 646 is the possible route of Texas State Highway 99, known as the Grand Parkway between Highway 146 and Interstate 45. It will become the third loop around the city of Houston. However, many businesses would have to be destroyed for the highway to be built along the FM, so a change to the plans is likely.

FM 649 was designated in Starr County on August 13, 1945. Its southern terminus has always been at US 83 in Garceno; its original north end was at the Starr–Jim Hogg county line. On March 31, 1948, it was extended northward into Jim Hogg County, to FM 496 at Randado; this section of FM 496 became SH 16 on August 31, 1965.[88] On August 5, 1954, the northern segment into Webb County was added, to what was then US 59 near Oilton; that section of US 59 became SH 359 19 days later. This extension replaced FM 1904, which went from FM 496 to US 59.[82][89]

Farm to Market Road 651 (FM 651) is a 60-mile-long (97 km) route located in Garza, Crosby, and Floyd counties.

FM 651 begins at an intersection with SH 207 in Post. The highway runs northeast and turns north just before the FM 261 intersection. FM 651 turns northwest just north of FM 2794 and turns north again near Crosby County Road 214. The highway enters the city of Crosbyton where it meets US 82/SH 114. FM 651 predominately runs north before ending at Floyd County Road 232.

FM 651 was designated on August 23, 1945, from Crosbyton southward 10.0 miles (16.1 km). On October 14, 1946 (agreed on May 12, 1947), FM 651 was extended north 5.7 miles (9.2 km) to Big Four School. On July 20, 1948, FM 651 was extended northward 2.0 miles (3.2 km) to White River Canyon. On May 23, 1951, FM 651 was extended south 9.5 miles (15.3 km) to a road intersection. On November 20, 1951, FM 651 was extended east 3.0 miles (4.8 km) to Kalgary. On December 17, 1952, the section of FM 651 from 3 miles (4.8 km) west of Kalgary to Kalgary was renumbered FM 2082 (now FM 261). FM 651 was extended north to US 82, replacing FM 151, and southwest to FM 122 (now SH 207), replacing FM 1618. On April 14, 1959, a spur connection in Lakeview was added.

Ranch to Market Road 652 (RM 652) is a 58.6-mile-long (94.3 km) route in Culberson, Reeves, and Loving counties near the New Mexico state line. Its western terminus is in Culberson County at US 62/US 180.[93] The route travels east into Reeves County, intersecting US 285 at Orla.[94] RM 652 then crosses the Pecos River into Loving County before ending at Eddy County Rd. 1 at the New Mexico state line.[92][95]

On May 23, 1951, Farm to Market Road 652 (FM 652) was assigned to a 6.5-mile (10.5 km) road from US 285 at Orla, northeastward. On November 21, 1956, it was extended northeastward 10.0 miles (16.1 km) to its current eastern terminus at the New Mexico state line. On February 27, 1958, it was redesignated RM 652 and extended 53.0 miles (85.3 km) westward from Orla to US 62 south of Pine Springs. On July 25, 1960, the western terminus was adjusted, so that RM 652 now met US 62 north approximately 10.0 miles (16.1 km) northeast of Pine Springs. This shortened RM 652 by 5.5 miles (8.9 km). On June 3, 1975, the western terminus was moved to the northeast again to its current location. The 1960-defined section of RM 652 between US 62 and RM 1108 was cancelled, and the section of RM 1108 from US 62 near the New Mexico state line southeastward 5.2 miles (8.4 km) was transferred to RM 652.[92]

Farm to Market Road 655 (FM 655) is located in Brazoria County. It provides access to the Texas Department of Criminal Justice's Ramsey, Terrell, and Stringfellow units. The road itself is approximately 5 miles (8.0 km) long, and at the western terminus, two spurs to the north and south provide prison access. The spurs have a combined length of around 2 miles (3.2 km).

FM 655 begins as two spurs at the prison complex; the mainline of FM 655 follows the northern spur while the southern is designated FM Spur 655. The two spurs travel through farm fields before joining. From here, FM 655 continues east through farmland within the prison complex. The highway then heads into Bonney and ends at FM 521.[98][99][100]

FM 655 was designated on August 24, 1945, to run from SH 288 (now FM 521) west to the Ramsey Prison Farm. On January 11, 1980, FM 655 was defined onto its current alignment, with the southern spur added.[98]

Farm to Market Road 659 (FM 659) is located in El Paso. It is 9.8 miles (15.8 km) long and known locally as North Zaragoza Road.

FM 659 begins at an intersection with FM 76 in southeastern El Paso, with Zaragoza Road continuing south to the El Paso Ysleta Port of Entry at the Ysleta–Zaragoza International Bridge. The highway travels in a slight northeast direction and crosses I-10. At I-10, FM 659's name briefly changes from Zaragoza Road to George Dieter Road. The highway turns right at George Dieter Road, with the Zaragoza Road designation continuing. FM 659 travels northeast through a heavily developed area of the city, passing by many residential areas and commercial shopping centers. FM 659 turns right at Montwood Drive before briefly traveling along the frontage road of Loop 375. Past Loop 375, FM 659 resumes running in its northeast direction before ending at US 62/US 180 near Homestead Meadows South.

FM 659 was designated on September 4, 1945, along its current route. An 2.7-mile (4.3 km) extension south from FM 76 to the Rio Grande was proposed on December 16, 1948, but cancelled on February 25, 1954. On June 27, 1995, the entire route was redesignated Urban Road 659 (UR 659).[105] The designation reverted to FM 659 with the elimination of the Urban Road system on November 15, 2018.[6]

Farm to Market Road 660 (FM 660) is located in Ellis County.[107]

FM 660 begins in rural eastern Ellis County at an intersection with SH 34 just over 1 mile (1.6 km) east of Ennis. It travels northbound from the east–west stretch of SH 34, bridging Fourmile Creek before it banks east as it merges onto Crisp Road. As it passes through the unincorporated community of Crisp, it then banks north and snakes towards an intersection with FM 813. At this intersection, FM 813 terminates as FM 660 banks east through Bristol, before banking north and making its way down Sugar Ridge. As it travels northbound, FM 660 briefly makes its way through the Trinity River Floodplain and crests over a levee locally known as "The Bristol Bump" because of its sharp and sudden crest potentially sending unsuspecting drivers airborne for a brief moment. FM 660 then travels northeast towards Ferris through the foothills bordering the Trinity River Floodplain, intersecting with FM 710 roughly 6 miles (9.7 km) northeast of Bristol and 2.5 miles (4.0 km) east of Ferris. FM 660 then intersects with Interstate 45 just before reaching its northern terminus with Business Interstate 45 in downtown Ferris.

FM 660 was designated on August 31, 1945. It consisted of an 8.0 miles (12.9 km) stretch connecting Bristol to the SH 34 intersection.[107] The northern extension to Ferris was later added on April 1, 1948, bringing FM 660 to its present-day length.

Farm to Market Road 662 (FM 662) is located in Midland County.

The current FM 662 was designated on September 26, 1979, from FM 1369 (now SH 158) to Industrial Avenue at of distance of 3.2 miles (5.1 km). On August 29, 1989, the highway was extended 2.1 miles (3.4 km) to FM 1788. On June 27, 1995, the entire route was redesignated Urban Road 662 (UR 662).[110] The designation reverted to FM 662 with the elimination of the Urban Road system on November 15, 2018.[6]

Farm to Market Road 664 (FM 664) is located in Ellis County.[112]

FM 664, known locally as Ovilla Road, is a major access road for the northern sections of Ellis County. It begins at Bus. US 287, the former route of US 287 in Waxahachie.[113] It briefly travels north along the de facto frontage road for southbound I-35E at exit 401B. After passing the interstate, the route continues north approximately nine miles into Ovilla, where it makes an abrupt right-hand turn and continues to the east for the remainder of its length.[114][nb 10] It crosses I-35E again (passing over the Boxcar Willie Memorial Overpass) and also SH 342 in Red Oak before terminating at FM 983 near Ferris.[112][115]

FM 664 was designated on August 31, 1945, and ran from near Waxahachie to Ovilla, with a southern terminus at US 287 (later Loop 528, now signed as US 287 Business).[116] It was lengthened to US 77 (now the I-35E freeway) on September 20, 1961. An extension east 4 miles (6.4 km) on June 1, 1965, and another extension to Ferris on June 4, 1970, brought the route to its current length.[112]

Farm to Market Road 665 (FM 665) is located in Jim Wells and Nueces counties.[118]

FM 665 begins in downtown Alice, at an intersection with SH 44 / SH 359.[119] The route travels to the south along Cameron Street before turning to the east, and passes Alice International Airport before entering Nueces County. FM 665 intersects US 77 (Future I-69E) in Driscoll and passes through the town of Petronila before turning more toward the northeast to enter Corpus Christi.[120] The route intersects SH 357 in the outskirts of Corpus Christi before crossing the SH 358 expressway and entering downtown.[121] FM 665 ends at an intersection with Spur 544 (signed as a business route of SH 44).[118][122]

FM 665 was designated on September 10, 1945, from US 77 in Driscoll to SH 44 in Corpus Christi. It was extended to Alice on November 2, 1955, replacing a portion of FM 666 from Driscoll to current FM 666 and the entirety of FM 736 from FM 70 to SH 359, though signage did not change until the updated official travel map was given out.[123][124] On June 27, 1995, the portion east of SH 357 in Corpus Christi was redesignated Urban Road 665 (UR 665).[125] The designation of this section reverted to FM 665 with the elimination of the Urban Road system on November 15, 2018.[6]

Farm to Market Road 666 (FM 666) is located in Nueces and San Patricio counties. It begins at FM 70 in Bishop.[127] FM 666 travels north,[120] intersecting SH 44 in Banquete and FM 624 in Bluntzer.[128] The road crosses into San Patricio County at the city of San Patricio,[129] and near the end of its route is parallel to I-37 to its east. FM 666 ends in the city of Mathis at SH 359; the roadway continues as a business route of SH 359 through Mathis.[126][130]

FM 666 was designated on September 10, 1945, from SH 44 in Banquete southward and eastward to US 77 in Driscoll. On July 14, 1949, the designation was extended north to US 59 (present-day SH 359) in Mathis. On September 21, 1955, the section of FM 666 from US 77 to its current junction with FM 665 was transferred to FM 665. On October 31, 1957, FM 666 was extended south to its current southern terminus at FM 70.[126]

In 2018, the section of FM 666 between FM 624 and SH 44 was designated the Kollyn Gene Barton Memorial Highway. Barton, a Banquete High School student, was killed in a vehicle accident along the highway in 2016.[131]

Farm to Market Road 669 (FM 669) is located in West Texas. It extends in a northerly direction for 68.8 miles (110.7 km) from Big Spring in Howard County to Post in Garza County.

Beginning at a complex junction with Farm to Market Road 700 and Texas State Highway 350 on the north side of Big Spring, Farm to Market Road 669 initially runs for 15 miles (24 km) in a northerly direction across the level plains of the Llano Estacado, passing numerous cotton fields and rural farm homes. Near the intersection of FM 1785, FM 669 drops off the Caprock and enters the rolling ranch and oil country of Borden County. The undulating, broken land of Borden County was carved by numerous ephemeral tributaries of the upper Colorado River that typically originate as springs along the Caprock Escarpment to the west and generally flow across the county in an easterly direction.[136]

After crossing the Colorado River, about 5 miles (8.0 km) north of the Howard–Borden county line, FM 669 continues north toward Gail, the county seat of Borden County.[137] Near Gail, one passes two prominent erosional remnants of the Llano Estacado. To the south of Gail, one can see a conspicuous landmark known as Mushaway Peak (also known as Muchakooaga, Muchaque Peak or Cordova Peak); this small butte stands on high ground between Grape Creek and Bull Creek, two tributaries of the upper Colorado River.[138] A much larger mesa, called Gail Mountain, stands on the western edge of Gail and provides a scenic backdrop for this small town.[139]

In Gail, FM 669 crosses U.S. Highway 180, which runs west–east from Lamesa to Snyder and beyond. Continuing north, FM 669 draws closer to the edge of the Llano Estacado, which can be seen 5 miles (8.0 km) to the west. Approximately 6 miles (9.7 km) north of Gail is a junction with FM 2350, which leads to Fluvanna and the Brazos Wind Ranch, to the east.

Farther north, near the Borden–Garza county line, FM 669 reaches a high point that divides the drainage of the upper Brazos and Colorado rivers. Along this drainage divide, the land is highly denuded with many small buttes and hoodoos. Less than a mile north of the county line is a historical marker that describes an archaeological site where the "Garza Point" was first identified. These distinctive arrowheads were constructed from local flint, chert, and obsidian by Native Americans living and hunting in this area around A.D. 1440 to 1500.[140]

Around 5 miles (8.0 km) north of the Borden–Garza county line, FM 669 crosses the Double Mountain Fork, a major tributary of the upper Brazos River.[141] From the colorful sandy bed of the Double Mountain Fork, FM 669 climbs 450 feet (140 m) over a distance of 6 miles (9.7 km) as it ascends the Caprock to the high plains of the Llano Estacado. FM 669 remains on the level plains for a short distance of only 3 miles (4.8 km) before suddenly dropping off the Caprock and descending 200 feet (61 m) back to the rolling plains and to the town of Post, the county seat of Garza County. Within the city limits of Post, FM 669 terminates at a junction with U.S. Route 380.[142]

FM 669 was designated on September 24, 1945, from US 180 at Gail south 10.0 miles (16.1 km). On March 30, 1949, FM 669 was extended south 2.5 miles (4.0 km) to a county road. On November 20, 1951, FM 669 was extended to FM 1584 at Vealmoor. On May 5, 1952, FM 669 was extended to US 87, replacing FM 1857. On October 30, 1953, the section of FM 669 from the current junction with FM 1785 to US 87 was renumbered FM 1785. FM 669 instead extended south to SH 350 near Big Spring, replacing FM 817. On November 21, 1956, FM 669 was extended north to FM 1313. On May 1, 1965, the section of FM 1313 from FM 669 to US 380 was transferred to FM 669.

FM 676 begins at an intersection with FM 492 in northeastern Doffing. The highway travels in a generally eastern direction along Mile 5 Road and intersects SH 364 in La Homa, then enters Alton. In Alton, FM 676 intersects SH 107 and FM 494. State maintenance for the highway ends at an intersection with FM 2220 at the McAllen city limits.

The Alton, Texas bus crash occurred along FM 676 in Alton on September 21, 1989.[151]

FM 676 was designated on June 26, 1945, from SH 107 5 miles (8.0 km) north of Mission eastward 2.5 miles (4.0 km). On July 15, 1949, FM 676 was extended west 4.0 miles (6.4 km) to a road that would become part of FM 492 on May 23, 1951. On May 23, 1951, FM 676 was extended east 0.5 miles (0.80 km) to Taylor Road. On September 28, 2017, FM 676 was extended east 1 mile (1.6 km) to FM 2220.[152]

Farm to Market Road 677 (FM 677) is located in Montague County.[153]

FM 677 is one of the longest farm to market roads in Montague County, and is a two-lane route for its entire length. It begins in Forestburg at a junction with FM 455.[154] It travels northward through the rural eastern part of the county, reaching St. Jo and an intersection with US 82.[155] It continues northward, through the unincorporated communities of Capps Corner and Illinois Bend, close to the Cooke County line.[156][157] It briefly turns to the west before resuming its northward journey toward the Red River. The FM 677 designation ends as the route crosses into Love County, Oklahoma across the Taovoyas Indian Bridge; the roadway continues as Oklahoma State Highway 89.[153][157]

A spur route, FM Spur 677, is located in Illinois Bend, traveling northward from mainline FM 677 approximately 0.268 mi (0.431 km).[153]

FM 677 was designated on January 31, 1946, northward from US 82 in St. Jo approximately 5.3 mi (8.5 km). It was extended north 2.5 miles (4.0 km) on May 23, 1951, south 2.9 miles (4.7 km) on November 20, 1951, and again southward on December 17, 1952, to Hardy near the FM 1630 intersection.[158] The route's designation was extended further northward to 3 miles (4.8 km) north of Capps Corner on December 2, 1953, and to Illinois Bend on September 29, 1954; the same day also so the lengthening to Forestburg. The connection to the Red River was made on April 24, 1958, and the concurrency with US 82 in St. Jo was removed on June 30, 1961. The connection to Oklahoma was made on December 20, 1988. The spur connection was added on April 25, 1996.[153]

Farm to Market Road 685 (FM 685) is located in Greater Austin.[166]

FM 685 begins in Pflugerville at the northern terminus of Dessau Road and at the eastern terminus of FM 1825.[167] The route runs to the northeast through Pflugerville to an interchange with the SH 45 Toll / SH 130 Toll toll road. From here, FM 685 runs north along the frontage road of the toll road, before separating from SH 130 in southern Hutto. The route continues to the northeast before ending at a junction with US 79 in central Hutto.[168]

FM 685 was designated in Williamson County on May 15, 1946, on an existing roadway, running from US 79 at Hutto southward to the Travis County line. The designation was extended into Travis County and Pflugerville on December 17, 1952, to its current southern terminus at FM 1825.[166]

When the SH 130 toll road was constructed, the segment between Pflugerville and Hutto used the right-of-way of FM 685. The FM 685 designation was subsequently applied to the frontage roads of the toll road.

Ranch to Market Road 690 (RM 690) is located in Burnet County, along the east side of Lake Buchanan.

Farm to Market Road 691 (FM 691) is located in Grayson County. The highway is known locally as Grayson Drive in the Sherman–Denison metropolitan area.

FM 691 begins at an intersection with Perimeter Road near North Texas Regional Airport in Sherman and intersects FM 1417 just east of here. The highway passes Grayson College before sharing an overlap with FM 131. FM 691 straddles the Sherman-Denison line and crosses US 75 before ending at an intersection with SH 91.

FM 691 was designated on April 16, 1946, from Camp Perrin to US 75 (now SH 91). It was previously War Highway 12. On June 27, 1995, the entire route was redesignated Urban Road 691 (UR 691).[187] The designation reverted to FM 691 with the elimination of the Urban Road system on November 15, 2018.[6]
